Mark ALDENDERFER Institution: School of Social Sciences, Humanities, and Arts, University of California, Merced Title of Presentation:Modeling Forager Mobility on the Tibetan Plateau Abstract: Explaining how and when people moved onto the Tibetan plateau and then moved across and beyond it is a foundational research question. A review of the archaeological literature on early Tibet, however, reveals that the challenges posed by important ecological and geographical features, such as numerous interior high mountain passes, wide rivers, cold seasonal and diurnal temperature variation, and terrain unsuited to certain subsistence packages in high and narrow valleys, are rarely considered in models of human mobility. In this paper, I explore how models of forager mobility in high mountain environments can be used to create more realistic explanations o...

Although numerous articles on the genetics of Central Asian populations have studied the Central Asian Tajik, both the human history and genetic diversity of Chinese Tajiks remain poorly understood. This study provides the first batch of genome-wide genotyping data for over 700,000 single-nucleotide polymorphisms (SNPs), as well as mtDNA multiplex sequencing data in 64 Chinese Tajik samples from two neighbouring dialect groups (Wakhi and Selekur). We apply principal component analysis (PCA), ADMIXTURE, f statistics, qpWave/qpAdm analysis and Fst to infer a fine-scale population genetic structure and admixture history. Our results reveal a close genetic relationship between Chinese Tajiks and Central Asian and ancient Iranians, along with a slight admixture signal from East Asian populations. Although both Chinese Tajiks and Tajikistani Tajiks showed genetic similarities across their genome-wide data, significant divergences in the maternal lineage composition suggest that ancient Tajik peoples migrated to China and intermarried with indigenous groups. Additional maternal and paternal haplogroup analysis indicates that Chinese Tajiks retained strong western Eurasian related genetic lineages, suggesting that large-scale population movement and genetic admixture accompanied this journey to the east.

Their language is one of the Mongolian languages of Altai language family. And their origin has long been controversial. The results of Cluster analyses (multidimensional scaling analysis, dendrograms, principal component analyses, and networks) of Dongxiang population and other ethnic groups indicated that Dongxiang people is much closer to the Central Asian ethnic groups than to the other Mongolian. Admixture analyses also confirmed the result. This suggests that Dongxiang people did not descend from Mongolian, but from the Central Asian ethnic groups that have spoken Persian or Turkic language. This mismatch between paternal genetic lineage and language classification might be explained by the elite-dominance model. The ancestral populations of Dongxiang could be the Central Asian ethnic groups assimilated by Mongolian in language and culture.
